[Verse 1: Peter Cetera]
Lonely nights, empty days
Use me up so many ways
You came along and stole my heart away, mmm
I just want to hold you darling, tonight
Knowing that the love between us was right
I can't believe that you'd ever let me go, oh, no

[Chorus: Peter Cetera]
What can I say? What can I do?
I'm so in love with you
Got to be strong
But, for how long must I have this feeling?
It won't go away

[Verse 2: Peter Cetera]
Take me back to yesterday
I just wanna fade away
Closer to you than what we used to be
Are we really gonna let it die?
Close the book and give it one more try
I can't believe that you'd ever let me go, oh, no

[Chorus: Peter Cetera]
What can I say? What can I do?
I'm so in love with you
Got to be strong (I got to be strong)
But, for how long must I have this feeling?
Won't go away
[Chorus: Peter Cetera]
What can I say? What can I do?
I'm so in love with you
Got to be strong (I got to be strong)
But, for how long must I have this feeling?

[Outro]
What can I say? (Ohh)
I'm so in love with you
Got to be strong (I got to be strong)
But, for how long must I have this feeling?
Won't go away (Oh)
